TO ALL WHOM IT'MAY CONCERN Be it known that I, JOHKIALLEXBASSETT, of Salem, in the county ofEsse x, and State of Massachusetts, hav'e in'vented a new anduseful Improvement in Process 3nd Materials for Carburetting Gases; and I dohereby declare' the following to .he a full descriptionfif the same, reference being had to the drawing which illustrates one of the methods by which my inventi on may be used, and is a vertical section of the apparatus employed.

I received Letters Patent on the 1st day of January,1867, in which is described an improved material i 'or filling gas and air-carburetters, No. 60,670. This material is termed Excelsior, and consists of fibres ofwood, separated in the direction of the length of the fibre. The object of this application is to describes. method 3f more perfectly utilizing the valuable qualities of this material, of increasing its capillary power, and combining with it other substanceshaving absorbent properties' Some of the capillary materials used for holdinghydrocarbon-liquidsin suspension are of too dense a. structure to permit the free passage of the air' or gases through them, after they are'saturatedwith the liquid.

Sponge and leather are examples of this class of absorbents, but, on account of their capacity for retaining a large amount of liquid, their use in combination with more porous materials is desirable;

.I therefore take the cxcelsior, which has a loose and open structure, and retains its porosity in the carburetter perfectly, and mix with it small pieces of sponge,- scraps of leather, or small coke. These materials are retained in the fibres of the cxcelsior, and take up more of the liquid than the excelsior would if used alone, and the excess of liquid taken up saturates the wholemass, and produces a more powerful carburationi Instead of the cxcelsior, cane or other fibre, which has the requisite stiflncss and porosity, and which is not liable .to be broken down whensaturated with hydrocarbon, may be used, and the spon'ge,'or like material, mixed with it. But prefer, in most instaiices, to use the excelsior. Fine cotton orflax-fibre may be mixed with it, the whole mass beingthoroughly intermingled.

These materials may be used in the apparatus shown, which consists of a case, A, enclosing a wheel, B, divided into compartments by partitions. The capillarymaterial is packed closely in these compartments, and, as the wheel revolves, the mass is successively saturated with the hydrocarbon. The gas enters through the opening 0, and, passingthrough the compartmentsof the wheel, passes out at the outlet-pipe D. In carburetting coal-gas, the wheel is driven by the pressure of the gas,- but in carburettingmir, it may be revolved by any suitable power. I

The combined capillary material may be used in any ofthe desirable forms of carburetting-chambers in which capillaryagents are employed,

Having'thus fully described my inventionywhatI desire to secure by Letters Patcnt,"is"

l; The combination of absorbent materials having different capillary powers, for the purpose of holding hydrocarbon-liquids in suspension carbonizing air and'gases.

2. Garburetting air or gases by the combined capillary materials described and shown.

3. The apparatusshown and described charged with the materials specified, and used for the purpose set forth.
